Research on Error Analysis of Data throughput and BER for the Wireless OFDM PSK Network

Wireless communication is one of humanity’s greatest achievements. The key aim of wireless communication is to provide high-data-rate communication. The sidebands from various carriers can overlap and cause interference during this transmission over a wireless connection. OFDM counteracts these interfering signals. OFDM is a multicarrier technique that sends a high-data single stream over a series of low-data-rate parallel sub-carriers. The symbol length appears to increase as a result, reducing the effects of multipath spread delay. In addition, the cognitive radio is built to use the best channels in the periphery for spectral efficiency. It automatically identifies the channels in a wireless spectrum that are able to be drawn and then changes the reception and transmission parameters accordingly. The error analysis is presented in this paper in OFDM system error correction with PSK modulation using forward codes (Reed-Solomon codes and Bose–Chaudhuri–Hocquenghem codes) in order to obtain low BER, high data rate, and also tolerance to interferences in AWGN, RICIAN, and RAYLEIGH channels, and the result is stimulated using LABVIEW. Wireless networking, which uses free space as a communication medium, has become essential, and cognitive radio is a technology that has proven to be the best in developing wireless systems.
